Abstract
A second reason for this neglect is the form in which Descartes was led or compelled to present his soul doctrine in the Meditations. In some complex manner the Meditations is both a medieval, scholastic-Aristotelian writing, as well as the acknowledged founding writing of modern philosophy. It is traditional as "first philosophy" or speculative metaphysics of substance, and as Christian apologetics concerned with the salvation of the infidel. In accordance with both, the soul is a separate, immaterial substance with an immortal destiny unprejudiced by the fate of the body. On the other hand, the Meditations is novel or modern as quest for indubitable "foundations" of the edifice of the sciences. The goal of the edifice of science is however stated only in the non-apologetic or more secular writings: the "mastery and ownership of nature," or "the enjoyment of the fruits of the earth in this life without pain," or such a wisdom as depends on knowing that "the mind depends acutely on the temperament, and the disposition of the organs of the body...". It is tempting to distinguish two Cartesian soul doctrines, the separate and immortal soul of the apologetic Meditations, and a secular soul articulated mainly outside the Meditations and especially in the Passions of the Soul, where Descartes speaks "as a physicist," addresses "the whole nature of man", never mentions any doctrine of substance, and remains utterly unperplexed about the interaction of mind and body. While such a gross distinction proves to be not without a certain homely truth, it leads us away from the Meditations, the classic document of the discovery of the modern soul doctrine.
